Be it known that I, GUSTAV W. HAUsnR, a citizen of the United States, residing at Jackson, Madison county, and State of Tennessee, have-invented and discovered certain new and useful Improvements in Awning- Arms, of which the following is a specification." 7

My said invention relates to certain rmprovements in the details of construction and arrangement of. parts of arms for supporting awnings, particularly arms of the folding type by which the awning frame is folded st the side of the building while the awmng is rolled upon the roller under the housing, and it consists particularly in .bracket on the buildi features of construction whereby the central joint, or pivot, is'normally held slightly to one side of, or out of line with, a line drawn from the end of the arm to the pivot in the whereby the parts normally break and f0 d assoon as the operation of rolling up the awning is started,

all 'as will be hereinafter more fully described and claimed. 7 Referring to the accompanying drawing, which is made a part hereof, and on which similar reference characters indicate similar P a Figure 1 is-a sideelevation of the awmng arm as it appears attached to the side of the building and in extended position,

Fig. 2 a top or plan view of the same, and

Figs. 3, 4, 5, 6 and 7 detail views lllustrating parts of the device more clearly.

, In said drawings the portions marked A represent the wall or frame work around the windows of the building to which the awning is attached; Bthe roller on which the awning is mounted, and C the awning proper. All of said parts above referred to are, or may be, of any appropriate type and of a construction in common use. The means for operating the roller B for rolling up the awning C is not shown, such means being common and well understood.

The awning arm is composed of two parts 10 and 11 connected by a hinge, or pivot bolt 12. The upper end of arm 10 is provided with a connecting member 25 of cast metal having a hinge-part 26 connected thereto by a horizontal pivot bolt 27 Said hinge-part 26 is connected to a member 28 by a vertical pivot 15, and said member 28 is secured to bracket 13, by ahorizontal bolt 14 and serrated engaging faces between Specification of Ilc'ttcrsratent,

'take the load and reduce bracket 13 and member28, as most clearly shown in Figs 3. Said member 28 has a curved track 29 on which the upper end of .member 25 is adapted to. rest and travel.

Said member 25 has a ball'or roller 30 to ber 18, as best shown in Fig. 1, for the purpose of afiordin'g the necessary strength and rigidity, while the lower part 11 is a single member bolted to casting 21 at its upper end, and has a swiveled socket 16 on its outer end to which is attached the cross-bars 17 for supportin the lowerend of the awning.

e between the parts 10 1 The centra hi and 11 is formed 0 the casting 18 of a form more clearly shown in Fig. 4, and rigidly secured to the members of the part 10 of the arm, and having a semi-circular track 19' formed on the outside thereof on which a ball or roller 20, mounted in a socket in the under face of casting 21 at the upper end of part 11, is adapted to roll and thus obviate friction during the folding and unfolding movement between these parts.

The top surface of the track 19 is formed inclined from both ends to a point w, as shown in Fig. 4, at which point the ball 20 normally finds its rest, and said point is so located as to slightly break the joint formed by the hinge 12 out of a direct line between the point of the arm and the hinge at the upper end thereof.

the frictionv be- The swiveled socket 16 at the end of the arm also prevents any binding or strain at this point during the movement. The track 29 at the upper end on which the arm 10 moves and is supported, is also formed with a depression in its face, as at point y in Fig. 3, which cooperates with the depression in track 19 tohold the parts slightly out of line. By this construction an awning arm is provided which will serve to holdthe awning securely in an extended position,

yet is always normally ready to fold without manual attention or breaking of the joints, as soon as the operation of rolling the awning upon the roller B, is started.

In lowering the awning the arm will straighten out into position as shown in Fig. 1, the part 11 vibrating on its pivot 12 and track 19 until it finally comes to rest with the ball 20 in the lower part a: of the track 19 where it is maintained by gravity and in position for automatically breaking the arm when the closing operation is again started.

By this construction and arrangement it will be seen that when in rolled up position of the awning the parts 10 and 11 of the arms are folded together and the upper end of part 10 is swung around to the highest point on the track 29, which supports said arms in a substantially. horizontal position against the side of the building. When the awning is lowered, the roller 30 rolls down into the depression 3 in the track 29 which brings said arms to an inclined position, as shown in Fig. 1, and the art'll swings down on pivot 12 into exten ed position, as shown in Fig. l, the ball 20 resting in the depression w in track 19 and thus holding the two parts of the arm slightly broken around the pivot 12, as shown in Fig. 2. It will be understood that by adjusting the part 28 on the bracket 13 a greater or less angular position of the arms, when extended, can be secured. It will also be understood that there is one arm at each end of the awning, and that they are mounted to break around pivot 12 in corresponding directions and manner.

The parts, when lowered and extended, automatically find their normal positions by reason of the freedom of movement allowed between said parts, and the normal position being determined by the lower-most points as and y in the track 19 and 29 respectively.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:

1. Anawning arm composed of two parts hinged together, one part being provided with a track'in the arc of a circle upon which a bearing on the other part is adapted to rest and travel, said track being formed said parts are held in position to break and fold immediately upon starting the operation of rolling up the awning substantially as set forth.

2. An awning arm formed of parts hinged and adapted to fold together, one part carrymg a track adjacent to the joint and the other part bearing a member adapted to travel upon said track, said track being formed with a lower-most point where the bearing part normally rests and in a position to normally maintain the two arts of the arm sli htly out of line with eac other, substantial -y as set forth.

8. An awning arm structure comprising a bracket for supporting said arm in position for use and carrying a curved track, a member of said arm connected to said bracket by a vertical pivot and carrying a bearing adapted to rest and travel on said track, a second member hinged to said first member of said arm, one member being provided with a track at said hinge-point and the other with a bearing adapted to rest and travel upon said track, both of said tracks bein formed with depressions in their bearing faces in which the bearing parts of the respective members of the arm are adapted to normally rest and hold said parts slightly out of line with each other, substantially as set forth.

In witness whereof I have hereunto set my hand and seal at Jackson, Tennessee, this 7th day of January, A. D. nineteen hundred and nineteen. I
